Mr Fraser and his wife Teresa were also facing a charge of perverting the course of justice.

The couple were due to appear before magistrates on Monday.

It is alleged Mrs Fraser accepted responsibility for a speeding offence committed by her husband in Scotland.

The force today put out a statement today saying they were shocked and saddened by Mr Fraser's death and that their thoughts were with his family and friend. They also confirmed that Mr Fraser had been offered welfare support during his suspension.

It is the second tragedy to hit the force in 12 months, last December former inspector Toby Day and his wife and daughter were found dead at their home in Melton.
